Abrus precatorius goes by many common names, including but not limited to Jequirity, Crab’s Eye, Rosary Pea, John Crow Bead, Precatory Bean, and Indian Licorice.

The plant is a slender perennial climber that twines around trees, shrubs, and hedges. Its leaves are long and pinnate-leafleted. Its seeds are black and red and contain the toxin abrin.

Though native to Indonesia, Abrus precatorius is now found in many tropical and subtropical areas of the world, including the United States. When introduced to new locales, the species tends to become weedy and invasive.

Known as Gunja in Sanskrit and some Indian languages and Ratti in Hindi, Abrus precatorius is used as a traditional unit of measure, mostly by jewelers and Ayurved doctors. The seeds are valued in native jewelry for their bright coloration. In China, they are a symbol of love. In Trinidad, they are worn to ward off evil spirits.

Jewelry-making with Abrus precatorius is considered dangerous work. Death by abrin poisoning has resulted from finger-pricking while boring the seeds for beadwork.

Symptoms are identical in abrin and ricin poisoning. But abrin is more toxic by almost two orders of magnitude.

Abrin is a macromolecular complex consisting of two protein subunits termed A and B. The B chain facilitates abrin’s entry into a cell by bonding to certain transport proteins on the cell membranes. Once inside, the A chain shuts down protein synthesis.

I was eyeballing pictures of the assassin legume when my iPhone started bouncing across the table. I’d forgotten to switch it from vibrate.

“You’ll never guess what I caught.”

“Scabies,” I said.

“What the hell’s scabies?”

“I’m good, Detective Slidell. How are you?” Why couldn’t the guy ever open with a greeting?

“I was up, so I caught your NASCAR pal.”

It took me a moment to translate. “You’re working the Wayne Gamble investigation?”

“Concord asked for help in sorting the thing. You been watching the news? It’s a shitstorm.”

“Galimore said a lot of media were camped out at the Speedway.”

Slidell did the throat thing. At mention of the media? Of Gali-more?

Disregarding Slidell’s censure, I recounted my visit with Craig Bogan.

“And?”

“I wouldn’t be surprised if the guy keeps a spare bedsheet in his closet.”

“Meaning?”

“I think he’s a bigot.”

“Who don’t he like?”

“Anyone who’s not white and straight.”

“Uh-huh.”

I described the phone threat. If it was a threat.

“Where was Galimore?” Stony.

“Right there with me.”

As the words left my lips, I realized that was wrong.

“So what are you doing?”

I knew Slidell was referring to the call. Chose not to acknowledge.

“Researching abrin,” I said.

“You know what you are, Doc?”

“Crafty on the Internet.”

Slidell clucked disapproval but let it go.

“Looks like Gamble was doing some research of his own.”

I waited for him to explain.

“Grady Winge talked about a ’sixty-five Mustang, right?”

“Right.”
